I want to control several devices using one MCU. Each device will receive either 1V or 3V depending on the application. I want to use only 2 analog pins from the MCU to send either 1V or 3V to several devices at the same time.
Is there some kind of IC or solution that assigns either inputs (1V or 3V) to the proper devices simultaneously and can change the input of the device from 1V to 3V depending on the MCU command?
Unfortunately, the DEMUX allows the selection of only 1 output and using an I/O expander is not practical because I also need this solution for other similar MCU commands. Any suggestions?
